Default Passing gear?? Cable or actuator?

Gents

Don't have passing gear.....you know that old stomp the gas and you get that great growl and downshift from the auto....

do I begin by checking for cable adjustment off of the carb and throttle linkage area or.....is it actuator/vac oriented?


thanks in advance

turbo 400's had an electric switch on the gas pedal for kickdown, the same switch controls the air door for the cowl induction setups. The TH350 has a cable I believe. I don't know which transmission the 75 used though.

If it's a TH350 it has a detent cable. It either needs to be adjusted or replaced.

I'll have to get back under it and look some more. I sure couldn't see either when I was checking it out yesterday.

thanks

OK

as it turns out I have a turbo 400.
looked under the gas pedal and found a switch for the action which in turn goes to the unit on the left side of the trans.

Here is my question....looked at the electrical schematics and cant find a fuse for it.

Any help?

OK

Confirmed I have a turbo 400.
Checked all the fuses and all is good.
Took the switch off of the pedal, cleaned and checked it.
Removed the plug connection on the trans and cleaned it as well.

Now I have intermittent passing gear at lower speeds but still no UMPPH or pass above 50 mph.

Bad switch at the tranny?
